Why is my GreatWall GW3300 2TB lagging with RDR2 4K MODs?

Riding through Saint Denis, I kept getting these 0.4-second micro-stutters that are incredibly noticeable at 4K. My monitoring showed the GreatWall GW3300 2TB was struggling with the high-res textures, with random read latency swinging between 110-140ms, which just left the CPU idling. I tried disabling all unnecessary disk indexing services, but that only saved me a second on boot and didn't touch the stutters. I finally went into Device Manager, cranked the disk IO priority to 'High,' and locked my virtual memory to a 32GB high-speed partition. The RivaTuner frame time curve, which used to look like a saw blade, finally flattened out to 16-22ms. I did notice some background apps becoming unresponsive after the priority shift, but I fixed that by reassigning CPU core priorities. Drive temp is 44-52℃, and the frame generation is finally steady at 16-22ms.
